n.
Wound from the bite of a snake , especially a venomous one.
Nonvenomous snakes leave skin tears that may be treated like scratches. A person bitten by a venomous snake needs medical care as soon as possible. Antivenin must be specific to the type of venom , so the snake should be identified or accurately described. Different kinds of venom break down red blood cells or attack the nervous system, causing paralysis . Local tissue destruction may lead to gangrene . First aid for snakebite seeks to keep the venom from spreading to the rest of the body. The bitten limb should be kept still below heart level with a broad, firm (not tight) bandage around it above the bite. Exertion and excitement should be avoided. Cutting, suction, tourniquets, and applying ice are not advised.
